We love when 3D printing collides with long-standing hobbies. Enter: Todd Schlemmer, our September Hacker of the Month, and his ardour for pinhole cameras and pictures.
Schlemmer has been constructing pinhole cameras for a number of years out of conventional carpentry and papercraft. He began 3D printing his cameras in 2012 as soon as he constructed his Printrbot Plus package: “I used to be delighted by my preliminary outcomes,” states Schlemmer, “and I’ve continued to develop and refine new digital camera designs.”
For those who do not know, a pinhole digital camera, in brief, is a light-proof case with a tiny gap on one facet which replaces the lens. Gentle is let in by means of the opening, creating an inverted picture of the skin world/topic onto the movie or reverse facet of the field.
Schlemmer now prints principally along with his LulzBot TAZ 4, in addition to a couple of RepRap machines he constructed from scratch. He usually makes use of PLA, however seeks any materials with excessive opacity, as he can not let any gentle into the chamber apart from the specified quantity by means of the pinhole.
“My cameras are known as terraPin,” describes Schlemmer, “they usually can be found in quite a lot of codecs and configurations.” He has designed many different parts for cameras, however the terraPin household seems most outstanding. Try among the terraPins beneath.
terraPin Prime
“The terraPin Prime is a 6×6 format, with a ‘focal size’ of about 27mm,” explains Schlemmer, including that “tright here isn’t any point of interest in a pinhole digital camera, however the time period is equally as helpful for calculating angle of view and movie quantity.”
This digital camera is able to photographing each vertically and horizontally at about 90 levels, which may be very broad. “The Prime makes a basic pinhole publicity with darkish corners and a shiny middle,” he describes, clarifying that that is as a result of “variation within the quantity of sunshine that hits the movie throughout the body.”

terraPin Kaiju
Schlemmer states that the terraPin Kaiju “makes pictures which can be unimaginable to make with a hard and fast lens digital camera,” clarifying that “because the movie is curved, the body could be very broad with a uniform publicity throughout the whole body.”
The Kaiju is a 6X18 panoramic digital camera with a radially concentric pinhole and a round movie ‘airplane’ – this permits the consumer to seize actually broad pictures in a single shot.

terraPin Bijou Sidewinder
The Bijou Sidewinder is a variation of the Bijou, which “shoots an oblong 6×4.5 body and will get 16 pictures per roll of 120 movie,” says Schlemmer. When the Bijou is used repeatedly, it shoots in portrait orientation, which is basically a vertical shot.
“The Sidewinder variation permits for mounting on a tripod in both panorama or portrait compositions,” he explains, “when taking pictures panorama, the knobs are on the facet, thus the title.” So, with the Sidewinder, you get the very best of each vertical and horizontal pictures.

terraPin 2-Headed-Turtle
Primarily based on his authentic 6×6 terraPin, Schlemmer developed a stereo pinhole digital camera dubbed the 2-Headed-Turtle. “This digital camera makes a stereographic pair of exposures concurrently,” he states, increasing that “the two exposures are 61mm aside, which may be very near the gap between human eyes, so the 3D impact feels pure when viewing.”
On the 2-Headed-Turtle’s web page on Thingiverse, Schlemmer explains that “to view the stereo pictures, you may “trick your eyes” whereas adjoining prints, or you should use a viewer designed for both slides or prints.” For the trick, isolate the image, and cross your eyes – the middle picture will look 3D. “It is superior,” smiles Schlemmer. We fully agree – strive it beneath!

These are only a few examples of Schlemmer’s rising digital camera assortment. Now we have a couple of posted in our Design Library, or you may examine them out on Thingiverse.
